The sum of a number, n, and 8 is multiplied by -4, and the result is -12. What is the number? pls hlp you'll get 12 points

n = -5

n = 1

n = 5

n = 11

- 4 × ( n + 8 ) = - 12

Divide both sides by - 4

( - 4 × ( n + 8 ) ) ÷ ( - 4 ) = - 12 ÷ ( - 4 )

Simplification

( n + 8 ) = 3

n + 8 = 3

Subtract both sides - 8

n + 8 - 8 = 3 - 8

n = - 5
